In order to rectify the existing acoustic defects of the lecture hall of Wen-Yuan Building in our university, a series of acoustic measurements were carried out, and analysis and a scheme of reconstruction was proposed therefrom, After completing the alteration according to the new designs in the summer of 1956, the hearing conditions of the hall were found to be greatlly improved. The author pointed out, however, that due to the lack of experience in this kind of work and to the insufficiency of acoustic instruments, there are still certain defects, the remedy of which would require further research work. Ⅰ. Introduction Ⅱ. A general description and analysis of the lecture hall before alteration. Ⅲ. Analysis and improvement from the view of geometrical acoustics. Ⅳ. Reverberation time. Ⅴ. Sound intensity distribution after alteration. Ⅵ. Noise reduction. Ⅶ. Some unsolved defects and problems.

为改善本校文远楼大讲堂内的音质缺陷,我们曾进行了一系列的音质测定和分析工作,并作了改建设计。1956年暑改建完毕以后,基本上已能符合听讲的要求,听者一般都感到清晰和满意。由于声学仪器和实际经验的不足,工作中尚存在着一些缺点和问题,在本报告中亦一一提出,以待今后继续加以研究解决。Ⅰ.绪言。Ⅱ.现况介绍和分析。Ⅲ.从几何声学上加以分析和改进。Ⅳ.混响时间的改进。Ⅴ.改建后的声强分布。Ⅵ.降低噪声的措施。Ⅶ.工作中存在的问题和缺点。

In the paper, we present three dynamic methods for measuring the elastic properties ofglasses, i. e, resonance method with acoustic frequency, composite vibrator method and me-thod of measuring ultrasonic velocity. The elastic properties of a series of inorganic oxide glasses with quite different compo-sitions are measured. Some modifications and improvements of the system for calculatingthe elastic properties of the glasses are made by means of the measured results. With our data of partial elastic properties of oxides in glasses, the Young's modulusand shear modulus of a series of silicate, borate and phosphate glasses are calculated. Incomparison with those calculating methods adopted abroad in the seventies, it is shownthat our method is simple, versatile and highly accurate.

本文介绍了我们研究和建立的声频共振法、复合振子法和超声测速法等三种玻璃弹性的动力学测定方法。 测定了一批成分变化较大的无机氧化物玻璃的弹性,利用测定结果对无机氧化物玻璃的弹性计算体系作了必要的修正和完善。 应用提出的氧化物部分弹性数据,核算了一系列硅酸盐、硼酸盐和磷酸盐玻璃的弹性模量和剪切模量,并和七十年代国外提出的计算方法作了比较。结果表明,我们提出的计算方法具有适用范围广,方法简单和精度高等优点。

On the basis of collecting structural features of the main components about several decades of medium and light-duty highspeed diesel engines whose bore diameter being 80-160mm, the author, in his article, investigates their common peculiarities, analyzes and search for history and tendencies their developments as well as offers several corresponding statical charts. He also explains with emphasis that "Rigidity design concept" is one of the guidethoughts which governs the design and improvement of main components of modern high-speed diesel engines; a great variety of structural versions are illustrated to describe ways of carrying it into practice. Meanwhile, synthetical comments are made on advantages and shortages of these versions. Author's own design points of view are presented herein, too. In the article, he gives the necessary explanation pertaining to new materials and new technologies as well.

本文在汇集了缸径为80~160毫米的几十种现代中小型高速柴油机主要零部件结构的基础上,归纳、研究了它们的共同特点,分析、探索了它们的发展过程与趋势,提供了相应的统计图。文中着重阐明了“刚性设计思想”是设计、改进现代高速柴油机主要零部件的重要指导思想,列举大量实例介绍了贯穿这一思想的各种具体结构措施;并对这些结构的优缺点作了综合评述,提出了作者对这些主要零部件的设计观点。文中还对有关的新材料,新工艺作了必要的阐述。
